HoneywellHRF-K2 Household Odor & Gas Reducing Pre-filter (Filter K) - 2 Pcs - For Air PurifierCompact by Design (Amazon-developed Certification)

They work well.

Does improve the air quality and a good value for the money you do have to cut to size.

works great

need these to continue to clean the air I breathe

The filters fit and work fine. I wish however, I would have purchased a cleaner that didn't require purchasing filters. My mistake.

All is good

Great

The following filter is not a Honeywell filter. It is an after market air cleaner replacement filter by All-Filters Inc. If you are looking for a true Honeywell air filter, do not order.
